The page says previously Australian Air Express, well no,it was never Australian Air Express. But anyhow,

The reviews here that say the item went to a post office for collection, ISNT startrack express but Startrack Premium or other services, delivered by Australia Post contractors and drivers, not Startrack express. If you not sure, check the SERVICE on your tracking, if its NOT "Express", it is not Startrack, but Australia Post. They do ALL premium, fixed price premium, international, next flight, on and on. Startrack Courier is not Startrack express either, but a complete different business. They do same day metropolitan deliveries. Some or almost all reviews here are not anything to do with StarTrack "Express" at all, but probably Startrack Premium(Australia Post delivery service) or Startrack Courier(owned by Australia Post).

Startrack Express can accept items from the other, that are not their own, to assist, as they are owned by THE other business, just like taking a very remote EXPRESS delivery to a post office as a arranged redirection by startrack express receiver,they will assist.

Check the service on your tracking and then review it on the right page.
